About the role

  • Have hands-on experience training and fine-tuning large transformer models on multi-GPU / multi-node clusters.
  • Are fluent in PyTorch and its ecosystem tools (Torchtune, FSDP, DeepSpeed) and enjoy digging into distributed-training internals, mixed precision, and memory-efficiency tricks.

Responsibilities

  • As a Model Training engineer, you will design, build, and scale the post-training pipelines that turn a general LLM into a brand-fluent, production-ready assistant.
